Question

If > ; show that − = 99( − ).​

Answer 1

Step-by-step explanation:

Given: a>c

To show : abc−cba=99(a−c)

Proof: abc=100a+10b+c....(i)

(By using property 3)

cba=100c+10b+a....(ii)

(By using property 3)

By subtracting equation (ii) and (i), we get

abc−cba=100a+c−100c−a

abc−cba=99a−99c

abc−cba=99(a−c)

Therefore, it is proved.
